The wait for Google to bring their browser over to the Mac and Linux platform is finally over, with a new release of Google Chrome today. Google Chrome for Mac is still in beta, so users should still be cautioned that the build may not be completely stable.

Google Chrome 4.0 beta offers gallery support for users that want to customize the look and feel of their browser; the gallery support is identical to the Windows version. However, Google Chrome for Mac relocated the toolbar buttons to the top in the OS X version.

Google will be releasing regular updates for not only the Windows client, but now the Mac and Linux platform. Google Chrome for Windows is said to graduate to 4.0 and be out of beta on January 12.

Chrome 4.0 supports extensions, a similar function to Mozilla Firefox add-ons, something that helped with the wide adoption of Firefox.

Extensions for Windows and Linux are all now live in Google Chrome 4.0 beta. Users can browse more than 300 extensions in their gallery; Mac extensions should be beta available soon, once all the kinks are worked out.
